A Vision for a Commercial-Scale Rooftop 'Farm' Nears Completion

Most people would not consider January an ideal time to plant crops, especially January in Montreal. But for Mohamed Hage, Kurt D. Lynn and Howard Resh, timing is one of the proof points of their project -- a commercial-scale rooftop greenhouse that's designed to yield produce year-round for an urban community.

Entrepreneurs Hage and Lynn and horticulture and hydroponics expert Resh are the brains behind Lufa Farms, which unveiled details last week about its 31,000-square-foot greenhouse being constructed atop a two-story office building in Montreal's Marché Central neighborhood.

Construction of the specially designed greenhouse began in July and is expected to be complete before year's end. Planting is scheduled to begin in January. On that timetable, the first crops would be harvested six weeks later.

"We're right on the threshold of completing the first commercial-scale rooftop greenhouse," said Lynn, Lufa Farms' co-founder and vice president, in an interview before taking the wraps off the project. "If it works in Montreal, it will work anywhere."

GreenerBuildings.com and GreenBiz.com have featured several articles on urban agriculture: farms called VertiCrops that mostly have been planted on the ground and were recognized by NASA for fostering water sustainability, the prospects for soaring high rise farms of the future, and another rooftop greenhouse business called Sky Vegetables, which was the subject of a piece last fall by GreenBiz Executive Editor Joel Makower.

While the idea of urban farming isn't new -- small-scale rooftop farms and herb gardens are key draws for green restaurants such as Uncommon Grounds in Chicago -- Lufa Farms lays claim to being the furthest along with a large-scale operation.

According to Lynn, he and his colleagues started batting the idea around about three-and-a-half years ago.

"The economics of food today forces us into compromises," Lynn said. "If I'm shipping things 2,000 miles, all along the way I'm increasing the handling of the food, affecting its taste, its freshness. It's a long food chain. My children don't know what a true tomato tastes like.

"Our goal simply is to be a neighborhood food source and raise the bar on the issue of traceability. We think it's important that people know where their food comes from, that they can say, 'Yes, I can see where my food is grown. It's grown right over there.' "
